TF246017: Team Foundation Server could not connect to the database

A colleague forwarded me the following error message:

clip_image002

The problem occured when he tried to create a branch, but only on this specific project we had issues.

Time to log on the TFS server and check the Event Log. There I found the following error message:

DESCRIPTION: SQL Server Assertion: File: , line=951 Failed Assertion = 'IS_OFF (BUF_MINLOGGED, m_buf->bstat) || pageModifyType != PageModifyType_Contents || GetPagePtr ()->IsTextPage ()'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.

This error message brought me to the following Connect ticket: https://connect.microsoft.com/SQLServer/feedback/details/3005568/sql-server-2016-merge-statement-fails-when-running-db-in-simple-recovery-model

I first tried to install all possible updates but no luck, the issue remained. Then I saw that in the ticket they mention switching to the Full recovery model. I tried that and it seemed to work.

Now

If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
